【摘要】：该文针对移动P2P网络中节点表现出来的自私性,并结合移动P2P网络的资源受限、自组织以及开放性等特点,提出一种基于不完全信息的双方叫价拍卖模型的节点激励策略—DAIP。该激励策略采用虚拟货币的支付方式,节点根据其拥有的虚拟货币量、自身资源状态和消息属性对每次消息转发进行估价,然后根据估价与博弈策略给出相应报价。通过博弈分析给出了DAIP策略的线性策略贝叶斯纳什均衡解,使各节点为最大化其自身利益而积极参与消息转发合作,从而促进网络系统中消息转发合作的成功。分析与实验结果表明该激励策略能够降低系统的能量消耗,提高整个网络系统的消息转发成功率,提高系统的整体效用。
[Abstract]:In view of the selfishness of nodes in mobile P2P networks and the characteristics of resource limitation, self-organization and openness of mobile P2P networks, this paper proposes a node incentive strategy based on incomplete information based on the auction model of two-party bidding-DAIP.. The incentive strategy adopts the payment method of virtual currency. The node evaluates each message forwarding according to the amount of virtual currency, the status of its own resources and message attributes, and then gives the corresponding quotation according to the valuation and game strategy. The Bayesian Nash equilibrium solution of linear strategy of DAIP strategy is given by game analysis, which makes each node participate actively in message forwarding cooperation in order to maximize its own interests, thus promoting the success of message forwarding cooperation in network system. The analysis and experimental results show that the incentive strategy can reduce the energy consumption of the system, improve the success rate of message forwarding in the whole network system, and improve the overall utility of the system.
